I've got Windows 8 Pro on my home machine. I want to have a Windows 7 Professional VM running under Hyper-V, and I want the VM to have full internet access. My physical machine has a wireless network adapter I use to connect to a router.

Here's what I've done so far:

In Hyper-V Manager, I've created a new External Virtual Switch, which is connected to my wireless network adapter. If I look in Windows 8's Network Connections page, I can see it's created a virtual ethernet adapter and a network bridge, and my wireless adapter is now bridged.

I've created a Windows 7 VM, and in the Hyper-V settings I've set it to use the virtual switch.

When I log into the VM, I have a network, but it's "unidentified" and has no internet access. What am I missing? Is it something to do with the "VLAN identification" settings? I'm not quite sure what these are about.

This is a great description, but it's exactly what I did. I did manage to get it all working though, I'll check at home this evening and either add an answer or mark someone as correct.

Not exactly sure how I got it working, I think I'd ticked the "Enable virtual LAN identification" box and then unticked it whilst the VM was running - for some settings like this, the VM needs to be off/restarted to take effect.

Anyone looking for the "Switch Manager" it's no longer under Action - instead right click the computer name (in the left area)

Another trick as detailed in this question Windows 8 Hyper-V network not working on host is that this may not work over wireless... re did the setting several times nothing - set up an ethernet adapter - worked straight away. [quick edit to say of course I'd set up separate virtual switches for the two physical adapters...]
